We’ve been busily working on these discovery layer interfaces since last November. The aim was to build two discovery layers providing WW1 related content that can support researchers and teachers interested in the subject. As noted previously, to achieve an acceptable response speed we’ve had to make a number of technical compromises. The response time is not ideal, but we’re happy that we’ve now got some good looking results and we’ve been able to help JISC and Discovery with assessing the case for aggregated open data. We’re pleased to have ended up with a good number of data sources in the API, currently at eleven.
